UP is a relative term. It means "further from the ground", or more exactly, "further from Earth's centre". Buckminster Fuller suggested using 'out' and 'in' for 'up' and 'down'. Presumably, people in orbiting laboratories use 'up' and 'down' relative to their floor.
A step-up transformer increases voltage, while a step-down transformer decreases voltage.
A step-up transformer increases voltage, while a step-down transformer decreases voltage.
Yes, the down quark is slightly heavier than the up quark. However, the difference in mass between a neutron and a proton is not solely due to the difference between the down and up quarks. Other factors, such as binding energy and contributions from virtual particles, also play a role in the mass difference between the two particles.
The force exerted by a person on the ground is the same whether they are standing up or laying down, as it is determined by their weight. The only difference is the distribution and contact area of the force between the feet when standing versus the whole body when laying down.
Yes, there is a difference between positive and negative g-force. Positive g-force is the sensation of weight pressing down on you, like during takeoff in an airplane. Negative g-force is the sensation of weightlessness or forces pulling you away from an object, like in a roller coaster drop.
Ntahlaaahhh =='''
The difference between the depression and a recession is a recession is the down on an up and down rollercoaster. While the depression, there was no way to tell when it would end.
A hill is hard to get up and a pill is hard to get down
it speeds up and speeds down
A counter counts up, a timer couts down.
A step-up transformer increases voltage, while a step-down transformer decreases voltage.
One is hard up, and the other is soft down.
Suppressants speed your system up, while depressants slow you down.
Airplanes can not fly straight up and down or hover.
Dawn is when the sun is coming up, sunset is when the sun is going down
what is the difference between cut- in and cut -out
Positive acceleration ==> speeding up Negative acceleration ==> slowing down
